Yeah, probaby because that's the only thing he is good at, he is a delinquent in the game and son of a criminal in rl. I don't think he would be able to be a king even in the game, since the king is supposed to be smart enough to keep the whole class in control, but this crazy dude would probably kill everyone around and spend the rest of his life in prison :D
it would be a disaster if he accidentally got the king card, but i feel like he doesn't care, unless it's Tatsumi. From now on, Tatsumi is responsible for Senzaki's actions since he is the one who tempted him, and i do not like how tatsumi thinks right now. Lol ready yourself (esp. Yer ass) tatsumi, looks like you've got yourself a non-temporary escape. Lol
In the beginning of the chapter (or the previous one) Tatsumi says: "I shouldn't have met this guy". Well, that says enough, in my opinion.
I'm sorry, but i think Senzaki is the only one who is not driven by the game like omg he doesn't need the game to be that twisted or use it to his advantage. He's just Senzaki lol and i wouldn't mind something happening to Karino, we need to open up that young master's character more, ofcourse starting from his family; tatsumi.
